From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Currently when a call to intel_atomic_get_dbuf_state fails the
error value being returns is a potentially uninitialized value
in variable ret. Fix this by returning the error value of
new_dbuf_state.
Addresses-Coverity: ("Uninitialized scalar value")
Fixes: 3cf43cdc63fb ("drm/i915: Introduce proper dbuf state")
